Resumo: The tung tree (Vernicia fordii) plant belongs to the Euphorbiaceae family, is adapted to temperate clime, and needs about 350 to 400 chilling hours (below 7.2°C) for vegetative and flower buds differentiation. This species are cultivated with the purpose of extracting the oil, whose important characteristic is the quick drying, being widely used in the industry of paints and resins, and can also be used in the ornamentation of roads and gardens. Despite being present in the State for over 50 years, information about the vegetative behavior of the tung tree is recent. Existing commercial plantations are characterized by great variability and non-uniformity among plants, this fact occurs mainly because seedling production is from seeds. Thus, the objective of this study was to evaluate the phenology tung genotypes in four consecutive seasons, to identify interest features. The results show a variability of interest. The genotypes were identified show the greatest need of cold and/or heat for budding and flowering, a very important characteristic for cultivation in Rio Grande do Sul.

Essa espécie é cultivada com objetivo de extração do óleo, cuja característica importante é a secagem rápida, sendo amplamente utilizado na indústria de tintas e resinas, podendo também ser utilizado na ornamentação de vias e jardins. Mesmo a cultura estando presente no Estado a mais de 50 anos, informações referentes ao comportamento do tungue ainda são recentes. Os plantios comerciais existentes são caracterizados por uma grande variabilidade e não uniformidade entre plantas, tal fato ocorre, principalmente, devido a produção de mudas ser proveniente de sementes. Assim, o objetivo do trabalho foi avaliar a fenologia de genótipos de tungue, em quatro safras consecutivas, visando identificar características de interesse. Os resultados obtidos revelam variabilidade de interesse. Foram identificados genótipos que apresentam maior necessidade de frio e/ou calor para brotação e floração, característica muito importante para o cultivo no Rio Grande do Sul.Departamento de Diagnóstico e Pesquisa Agropecuária.
